The device is capable of withstanding high load forces due to a novel self centering reinforcing rail.

Abstract: A roller formed by a spindle and a tubular jacket has elastic sleeves for attachment of the jacket on the spindle. Each elastic sleeve consists either of a clamp-on sleeve fitted on the spindle, a clamp-in sleeve applied concentrically therewith in the jacket, and a rubber ring arranged between the clamping sleeves, or of a sleeve of undulated cross-section whose wave crests directed radially outward bear against the inner wall of the jacket while its wave crests directed radially inward bear against the spindle. Lastly the elastic sleeve may consist of a rim or ring of clamping pins angularly spaced apart which are arranged and fixed at regular intervals distributed over the annular space between jacket and spindle.

Abstract: A lighting fixture adapted to be mounted between parallel ceiling support grids includes a series of latches at the corners.

Abstract: The invention relates to a method and an apparatus for the straightening of drawn round stock. In conventional straightening methods, the round stock to be straightened is transported through the straightener with the entrance and exit in alignment, being thus straightened. With this procedure, large pieces at the beginning and end of the round stock to be straightened are straightened in an unsatisfactory manner and must therefore often be cut off before further fabrication of the round stock. To remedy this disadvantage it is proposed that for instance the deviation from the straight entry line forcibly obtained in the straightener arc by deflection, is maintained as the exit direction from the arc. To this end each round stock receiving device is oriented or can be oriented behind an exit die at least by its receiving elements in such a way that the round stock leaving the exit die enters such receiving elements or the next die series without appreciable changes of direction.

Abstract: The present invention relates to a method for the continuous firing of green ceramic articles, such as capacitors. In accordance with the invention a mixture of articles to be fired and heat resistant particulate matter in selected proportions is caused to descend a heated tube defining a furnace. Articles and particulate material such as sand are continuously introduced at the upper end of the furnace and removed at the lower end, after a predetermined dwell time within the furnace to effect firing. Removal is effected by progressively advancing a conveyer which is in partial blocking condition of the lower end of the furnace across the lower end of said furnace whereby the mixture of sand and fired ceramic articles is removed at a selected rate which is a function of the speed of the conveyer, whereby the dwell time in the furnace is closely controlled.

Abstract: A failure sensing accumulator device and to a system embodying the same.

Abstract: Known machines for the machining of crankshafts, in which the machining units for the machining of the crankshaft are supported and moved by operating crankshafts, are not adjustable to different offset angles of crankshafts to be machined. Therefore a machine is proposed for the machining of crankshafts with means for the guiding and taking along of a crankshaft to be machined and with at least two movable devices for the uptake of machining tools or systems, the devices being supported and moved by crankpins of two driven operating crankshafts consisting of several cranks and mounted on main bearing pins, where the individual cranks of each operating crankshaft are fixable relatively to each other and comprise two independent main bearing pins each and are mounted thereon for rotation relative to each other.

Abstract: The present invention relates to a fail-safe actuator of the type in which a piston riding in a cylinder is urged toward a port end of the cylinder by an energy storage spring. The piston is prevented from moving toward the port end so long as liquid remains entraped between the piston and port end, movement of the piston toward the port end resulting in shifting of a cable and consequent rotation of a quadrant about which the cable is arrayed to rotate a shaft. A rolling seal diaphragm is interposed between the piston and cylinder whereby leakage is prevented over protracted use periods, and the piston is isolated from liquid between the port and piston. Optionally, an annulus disposed between the piston and cylinder bears against the roll seal portion of the diaphragm preventing extrusion or permanent distortion of the diaphragm under high pressure conditions.

Abstract: The present invention relates to an apparatus and method for the automatic insertion of electronic components, such as capacitors, resistors and the like, into a printed circuit board or an equivalent matrix disposed at a insertion station. The apparatus is capable of rapidly and accurately removing electronic components particularly those having axially extending leads, from a bulk storage supply, forming the leads into the parallel spaced configuration necessary for insertion into a P.C. board, advancing the lead-formed component into a position within the P.C. board stripping the component from the insertion mechanism and reloading a further component into the insertion mechanism.

Abstract: The present invention is directed to an integrated circuit device comprising a lead frame having a ceramic capacitor mounted thereon and forming the support for a silicon chip bearing a multiplicity of circuits, including at least two power supply circuits namely a main power supply circuit and a secondary circuit.

Abstract: The present invention relates to a low cost method of fabricating capacitors within tight tolerance ranges. The method involves forming, by vapor deposition or the like, discrete electrode areas on an insulating substrate, and depositing a dielectric layer over the substrate and the areas between the electrodes. A further series of electrode are formed over the dielectric in partial registry with the first mentioned electrodes, and the substrate is thereafter diced to expose opposed edge portions of the resultant capacitors. The capacitors are terminated preferably by a sputtering technique, the sputtered material being insulated from contact with the edge portions of non-exposed electrodes by the deposited dielectric.

Abstract: The present invention is directed to an IC device of the ceramic encapsulated type wherein a power supply pulse dampening capacitor is embodied within the IC housing.
